Moulton ousted scandal plagued Rep. John Tierney (D) in the primary, 49 to 41% and faced a competitive general election from former state Senator Tisei.

An opponent of the Iraq war, Moulton served four tours in five years in Iraq. He was formerly the managing director of Texas Central Railway and has an MPA from the John F. Kennedy School of Government and an MBA from Harvard Business School.

The 6th district is Democratic at the Presidential level but was carried by Republicans for Senate and Governor.
